In an effort to distinguish between the two models, we determined the crystal structures of the urate complexes of the demolybdo-form of the D428A mutant of rat xanthine oxidoreductase at 1.7 A and of the reduced bovine milk enzyme at 2.1 A, the latter representing a reaction intermediate. The results clearly indicate the catalytically relevant binding mode of the substrate xanthine.
